GEARIN'G.

Specification of Letters Patent.

Application filed November 18, '1915. Serial No. 62,109.

To all whom it may concern: I Be it known that I, CLARENCE E. Mani.- HOPE, a citizen of the United States, and a resident of Chicago, in'the county of Cook and State of Illinois, have invented certain 1 new and useful Improvements in Gearing; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying. drawings, and to the letters of reference marked thereon, which form a part of this specification. j

This invention relates to improvements in gearing and consists of the matters herein-v after described and more particularly point ed out in the appended claims.

The gearing'is designed particularly for use in connection with a washing machine of the kind known as a pounder washer or vacuum washer,- in which a tool, usually in the form of a hollow cone, is fixed to the bottom ofan operating shaft or plunger by means of which it is given a vertical, reciprocating movement and, in most cases, at the same time an alternatlng, rotary move- I ment.

The object of the invention is to provide aneconomical and efl'icient gearing for the purpose intended by means of which the power, both to vertically reciprocate the operating shaft or plunger andalso to alternately rotate said shaft, is applied directly to the shaft (when such movement is de-' shaft of the washing machine. Fig. 4 is a perspective view of the same. Fig. 5 is a detail perspective view to be referred to more specifically later in the description.

Referring now to that embodiment of. my

indicates the tub of a washing machine which is supported on legs 11, has a fixed top 12, and a hinged lid '13. The washing machine tub shown is square but mili -ifestly. may: be. of any desired, form; The

tub and its hinged lid constitute the supports for the gearing.

As illustrated in the drawings, the lid 1 is hinged to the fixed top 12 of the tub by means of hinges 14, 14. a

15 indicates a horizontal shaft which provides the pintle of the hinges 14, 14, and

which is projected at I one side beyond the.

tub body. Preferably a reinforced bearing bracket 16 is fixed to the top of the tub near the side'at which the said shaft projects.

l7find1cates the operating shaft of the washing machine and 18"tl1e tool or pounder fixed at its bottom within the tub. body.

Patented Jan. 16, 1917.

The tool 18, as has been said, is preferably conical and hollow and in the present case. opens at its top to the outside air through the shaft 17 which is made hollow for that purpose, The specific details of this construction are not materialto the operation of the gearing. The shaft 17 depends through the tub lid and has bearing in a bracket standard 17 fixed to and rising from the top of the lid.

.19 indicatesa lever arm which, aswill appear, is operatively connected to the vertical shaft17. The lever, of which the member 19 is an arm, is in this case a bell-crank lever and is placed in substantially a horie zontal position, being rigidly connected. 7

with an upright socket arm 20 in which is jfixed a handle 21 in a familiar manner for grasping and operating the lever;

At the inner operating end of the lever arm 19 is provided a fork 22, which embraces the shaft 17. 28, 24 indicate the two horizontally extending tines of said fork.

One of the tines, namely, the tine 23, has a slot 23 in which engages a horizontal pin 17 that extends laterally from the shaft 17 The other tine 24 is pivotally connected in any suitable manner to a second horizontally extending pin 17 b on the shaft 17. The two pins are preferably placed diametrically opposite. The connection between the lever arm 19 and the shaft 17 as described, is such that when the lever arm has imparted to it a rocking up and down movement, a positive up and down movement will be given to the shaft 17. At the same time, by reason of the horizontal displacement of the pin 17 in the rocking movement of the arm 19'from its uppermost position to its bottommost position, a rotative swinging mpvement will. be imparted to the shaft 1 7,.-1n one d rection when the lever arm -19. is swung downward and in the opposite direction when the arm 19 is swung upward. The engagement of the pin 17 with the slot in the fork arm 23 provides for the positive engagement of the lever on both sides of the shaft 17 without interfering with the alternating rotary movement imparted to said shaft in the up and down movement of the lever. v

High speed balance wheel mechanism may be connected to the lever 21 in any convenient manner;- As shown, the shaft has fixed to it beyondthe tub, a lever arm 25 and this is connected by a pitman 26 to a large gear 27 rotatively mountedon the side "of the tub and engaged with a pinion 28 on the hub of a flywheel 29 which is also r0- I tatively mounted on the side of the tub.

Thus the rocking movement of the lever arm 19 will be imparted through the shaft 15 to the lever arm 25 and through said lever arm, will impart a continuous rotary movement at high speedto the fly wheel 29 in a familiarmanner; Such a mechanism provides for the operation of the machlne by a motor, as itywill be manifest that by con- ,necting up the wheel 29 to "a motor, the le- Ver arm 25 will be driven to. swing the lever arm 19 up and down at reduced speed so as to impart the required movement to the operating shaft. i

Any suitable means fordisconnecting the gearing when opening the lid may be used.

As shown, thelever arm 25 is provided with a joint connection with the shaft 15, such that it maybe operatively disconnected from 7 said shaftwhen it is desired to open the lid.

The lever arm 25. has a sleeve 25 at its top which bears uponthe end 15 of the shaft 15 (see, Fig. 5,. which showsthe two parts separated), and a set'screw 26 is threaded .through the sleeve 25 and is adapted to engage against a flat part 26 on the shaft end 154. Thus normally the lever arm is, rigidly connected with the shaft 15. When, how;

ever, the lid is to be opened, the set screw 26 is rotated to withdraw it from engagement withthe' flat part 26 on the shaft, whereupon the end 15 maybe rotated within the sleeve 25?, when it may be opened.

I claim as my invention 1. A gearing for washing machines and the like comprising, in combination with a support, an operating shaft depending into said support and capable of vertical reciproeating movement and of an alternating rotary movement, a lever arm, and means directly connecting said lever arm with said operating shaft by which the up and down movement of said lever arm is caused to vertically reciprocate saidoperating shaft and the I horizontal displacement of the means "connecting said lever armwith'said shaft is used to impart an '65 alternating rotary movement to said shaft;
